Description

A device for lifting sunken submarines (ships) relates to ship lifting equipment or to technical means for lifting sunken ships, especially submarines. The lifting of any object from the depth of the reservoir occurs in any position when it is necessary to save the crew.

A device for lifting a sunken submarine is known, comprising a vessel with hoisting ropes having grips at their ends and coupling devices mounted on the submarine made in the form of glasses for interacting with grips, where the glasses are mounted on a sturdy hull of the submarine and are located along it in several rows in the space between the strong and lightweight housings. Each glass is made round and has an internal tide on the upper side with an annular recess on its lower side and a thread for the lid that closes the glass, and each grip is made with two spring-loaded strips fastened by a bolt, and the end of the hoisting rope is fixed between these strips, the lower ends of which protrusions.

(see patent 2222467 B 63 C 7/00, 2002)

The disadvantage of this device is that the cable has a large diameter and can not be bent, and they need 30 pieces, in addition, the complexity and unreliability of the design.

A device for lifting a sunken ship is known, comprising a frame with a grip including arcuate elements pivotally connected to each other and kinematically connected to levers pivotally mounted on a common axis with arcuate elements at their ends, the frame being suspended from a surface vessel, this device is equipped with a container with an electrolyzer and compressors, elastic containers placed in these pontoons and communicated with the outputs of the compressors, as well as clamps with pyrodrives for interaction with the wreck, mounted at the ends of the arcuate elements.

(see patent No. 2025403 B 63 C 7/00, 1990)

The disadvantage of the device is observed in the tick capture. The boat should lie on perfect ground. It is not realistic to use it to lift submarines lying on rocky soil, in crevices, on corals, at great depths. Pressure difference not taken into account. When lifting, a break due to the lifting weight is possible. The design is unreliable.

A device for lifting a sunken object, comprising a load gripping element made with an axial longitudinal hole for movement along a conductor cable with the possibility of interaction with a docking station fixed to the sunken object. A conductor cable is connected at one end to a docking station, and at the other to a marker.

(see patent No. 20046423 B 63 C 7/00, 1991 g prototype)

The disadvantage of this device is the complexity and unreliability of the design.

The goal is to increase reliability and simplify the design.

The problem is achieved in that in the device for lifting sunken submarines (vessels) containing a load gripping element with the possibility of interaction with a docking unit fixed to a sunken submarine (vessel), the load gripping element is made in the form of an upper coupling device mounted on a rescue vessel, and the docking unit is made in the form of the lower part of the coupling device, which is installed on the sunken submarine (ship) with the help of a power ring, strip bandages and clamps. The upper part of the coupling device includes a monolithic base, trunnions, hydraulic cylinders, cables, winches and drawbar, which consists of an inner pipe inserted into the outer one and at the same time is fixed to hold it in a vertical position. The lower part of the hitch is mounted on a sunken submarine (vessel) using a power ring, strip bandages and clamps and includes a mushroom, a winch with a guide cable and floats. In this case, the mushroom has an oval shape with a cone-shaped neckline, hooks, for putting on the chain links and a rim that prevents the chain links from being removed from the hook, and allows docking (coupling) of the sunken submarine (vessel) lying on its side, on rocky soil or in crevices. The inner cut on the trunnion and the bevel of the lower part of the mushroom cap have the same cut angle, so that when gripping, they tightly pressed against each other. The axle, during the implementation of the coupling, the tip of the hook rests on the leg of the mushroom, which does not allow it to unbend when lifting. In addition, a monolithic base

made by welding six separate parts with tides, which facilitates the manufacture.

Thus, the claimed device for lifting sunken submarines (ships) meets the criterion of "novelty."

The essence of the utility model is illustrated in the drawing.

A device for lifting sunken submarines (ships) consists of a mushroom 1 (FIG. 1), a guide wire 2, an upper bevel of the mushroom cap 3, a lower bevel of the mushroom cap 4, the legs of the mushroom 5, rim 6, the mushroom hook 7, chain links 8, the base mushroom 9, the central hole of the mushroom 10, the conical cutout 11, the guide wire 2, the float 12, (option A) of the hook of the float 13, the eye 14, which is located on the guide of the cable 2 (option B), winch 15, (Fig 2) with a guide cable 2, power ring 16 (figure 3), holes for bolts 17, strip clamps 18, strip bandages 19, tides 20 (FIG. 4), a monolithic base 20a, a central hole 21, a shank 22, external

pipe 23, the inner pipe 24, the tightening ring 25, the holes for attaching the pins 26, the cylinder 27, the locking plate 28, the slots 28a, the pins 29 (Fig. 5), the tides for attaching the hydraulic cylinder 30, the hook of the pin 31, the tip of the hook of the pin 32, the lower cut of the trunnion 33, the upper cut of the trunnion 34, the link of the power cable 35 (Fig.6), the holes for attaching the power cable 36, the mounting bolt 37, the plug 38, the holes for the mounting bolt 39.

The utility model consists of two main parts: the upper part of the hitch and the lower part of the hitch. The upper part of the coupling device is installed on a special rescue vessel, and the lower part of the coupling device is installed on a sunken submarine (vessel) using a power ring 16, band ties 19 and clamps 18. The upper part of the coupling device consists of a pin 29, a monolithic base 20a, hydraulic cylinders 27 (six pieces), a guide cable 2, a catamaran winch (not shown) and a drawbar 23, 24. The lower part of the coupling device includes a mushroom 1, a winch 15 with a guide cable 2 and floats 12.

The lower part of the coupling device, which is installed on a sunken submarine (vessel), consists of the parts shown in figures 1, 2, 3. Figure 1 shows a detail in shape resembling a mushroom 1. The size of this mushroom 1 must be such as to withstand the expected loads. In the center of the mushroom 1, from the base to the top, there is a central hole of the mushroom 10 through which the guide cable 2 is passed. The length of the mushroom 1 should be about 4-5 meters, so that it is easier to install it in a vertical position when docking with the second part of the coupling device. Mushroom 1 must be secured on a sunken submarine (vessel) in such a way that around

there was no interference at a distance of the length of the mushroom 1, that is, there should be no add-ons that would interfere with the installation of the mushroom 1 in an upright position. One such mushroom 1 is fixed in the bow, the other in the stern of the vessel, at a distance of about a quarter of the length of the submarine (vessel) from the bow and stern. The top and bottom view of the mushroom 1 is shown in Fig. 1. The mushroom 1 in the lower part must have a rounded shape, which is necessary so that the mushroom 1 can be tilted in any direction, giving it a vertical position, since a sunken submarine (vessel) can lie on your side, nose up or down. Next, the submarine should be two winches 15 (figure 2) with a guide cable 2 of large length and two floats (barrels) 12, which are located in the bow and stern. The floats 12 are necessary so that in the event of a disaster they automatically detach from the sinking vessel and carry along the guide cable 2, drawn through the central hole of the mushroom 10. The floats 12 float, entraining the guide cable 2.

The mushroom 1 is attached with its lower part to the power ring 16 (figure 3). In the submarine, between the strong and light hulls in the bow and stern parts around the hull, strong bandage bandages 19 are made. On modern submarines, it is necessary to finalize the installation of the lower parts of the hitch. To do this, depending on the diameter of the submarine, steel strip bandages 19 and clamps 18 are made of the appropriate size, together with a power ring 16, a mushroom 1, a winch 15 and a float 12 fixed to them. The lower part of the coupling device (Figs. 1, 2, 3 ) put on the bow and stern of the submarine (vessel). The entire assembly is closed by fairings (not indicated in the drawing). Chain links

fixed on the basis of the mushroom 9 (figure 1) and so that they do not have the possibility of removal, they are on top, using the rim 6, is fixed. These links of the chain 8 are put on the power ring 16, (Fig.3) To the power ring 16 with the help of strip clamps 18 are connected steel strip bandages 19 (Fig 3).

Band clamps 18 are necessary in order to make it easier to connect the bandage bandages 19 to the power ring 16. Band clamps 18 are connected to the bandage bandages 19 with bolts 17. The number of links in the chain to each hook 7 of the base of the mushroom 9 (Fig 1) should to be the same. The chain length must be such that the mushroom 1 can freely lie in a horizontal position.

Figure 2 shows two options. Option A - with a float, option B - without a float. The second option is simpler.

In order to prevent “biting” of the guide cable 2 when the mushroom 1 is placed in a vertical position, a conical cut-out 11 is made in the lower part of the base of the mushroom 9 (Fig. 1).

The upper part of the coupling device is a monolithic base 20a (Fig. 4), having a central hole 21 from the base to the top for the guide cable 2. Through the side of the monolithic base 20a (Fig. 4), a slot 28a is made between the tides 20 for the locking strip 28 to the Central hole 21, into which the guide cable 2 is inserted. The slot 28a for the locking strip 28 should be slightly wider than the diameter of the guide cable 2. After the guide cable 2 is inserted into the central hole 21 of the monolithic base 20a (Fig. 4) , the slot 28a along the entire length should be closed by a locking strip 28 to the central

holes 21 of the monolithic base 20a. The monolithic base 20a should be powerful enough. Around the circumference of the monolithic base 20a there should be tides 20 with holes for fastening the pins 26 and links of the power cable 35 (Fig.6). The pins 29 (FIG. 5) are powerful grips, each of which must be spring-loaded with hydraulic cylinders 27. A simple way is to spring the pins 29 using springs (not shown in the drawing). The reinforcement of the hydraulic cylinders 27 (springs) should be such that when the upper part of the coupling device is tilted, the pins 29 are kept in a compressed state. The device of the lower sections of the trunnions 33 and the upper part of the bevel of the mushroom 3 allows the trunnions 29 to slide down the bevel of the mushroom 3 under the weight of the upper part of the coupling device.

The pins 29 will diverge until they reach the lower bevel 4 of the mushroom cap 1 and under the action of the springs or hydraulic cylinders 27, the hooks of the pins 31 will completely fit under the mushroom cap 1. The upper cut on the pin 34 and the lower bevel 4 of the mushroom cap 1 must have the same cutting angle (but vice versa), so that when gripping they are firmly pressed against each other. The tip of the hook of the pivot 32 should be sufficiently tightly pressed against the leg of the mushroom 5, so that the hook of the pivot 31 does not have the ability to unbend when lifting. It will be the tip of the hook of the axle 32 against the leg of the mushroom 5.

In order to make it easier to hold the entire upper part of the coupling device in the vertical position when lowering, the shank 22 (Fig. 4) must be on top of the monolithic base 20a (Fig. 4) on which the tightening ring 25 is fastened for fastening the hydraulic cylinders 27 and the guide tube (drawbar ) The drawbar is the outer pipe 23 and the inner pipe 24 of the upper part of the coupling

device (Fig 4). The shank 22, the tightening ring 25 should have slots matching the slot for the locking strip 28. The drawbar 23, 24 should consist of two pipes strong enough. Each pipe 23, 24 should have a slot along the entire length for introducing the guide cable 2. The outer pipe 23 is mounted on the shank 22 with the base after putting it on the shank 22. The inner pipe 24 is inserted into the outer 23 and it can be turned after the guiding cable 2 is inserted clockwise or counterclockwise, using the rotary knob in the upper part of the pipe, until the slot in the inner pipe 24 reaches the edge of the slot of the outer pipe 23. The rotary handle (not shown) of the inner pipe 24 is lowered and fixed. The inner pipe 24 in diameter should be equal to the diameter of the shank 22 and its lower end should rest on the shank 22. The monolithic base 20a (Fig. 4) of the pin 29, the fastening bolts of the links of the power cables 35, should be made taking into account the expected loads. The main load will fall on the power cables from the catamaran, the links of the power cables 35, axle 29 and mounting bolts. Each monolithic base 20a (figure 4) can be connected to 12 power cables. A monolithic base 20a can be made by welding six separate parts with tides 20.

Coupling device operation.

In a catastrophe of a submarine (vessel), when it begins to sink, the system should hold, holding the float 12 on the sunken submarine (vessel). The float 12 draws a guide wire 2. The winch 15 is open. A float 12 pops up. When the floats 12 are detected, the catamaran goes over the floats 12 so that

they were between the hulls of the catamaran. Cranes hook the floats 12 over the hooks of the float 13 and lift them aboard the catamaran. A special grip (not shown) capture the guide cable 2 in the lower part of the float 12 meters by 15-20, so that the upper part of the guide cable 2 is released from tension. Remove the free end of the guide cable 2 from the float 12 and insert it into the slot 28a for the locking strip 28, the central hole 21. Put on the shank 22 of the drawbar 23, 24, combining the slot on the outer 23 and inner 24 pipes with the slot 28a on the shank 22 and fix her. Then guide wire 2 is introduced and the inner pipe 24 is turned along its axis so that the slot of the inner pipe 24 goes beyond the slot of the outer pipe 23. Fasten the inner pipe 24 from its rotation along its axis using a rotary handle (not shown). The end of the guide wire 2 is fixed to the catamaran winch. And only then they remove the special grip.

When option B, when there is no float 12:

A) if the depth allows you to lower the diver to the sunken submarine (vessel). A diver, dragging a cable (halyard) unwound from a catamaran, reaching a sunken submarine (vessel), hooks this cable (halyard) onto the eyelet 14 (ring) of the guide rope 2 with a carabiner at the end of the cable (halyard).

B) if the depth of the sunken submarine (vessel) exceeds the capabilities of a diver, then the docking (hook) is carried out using a mini-submarine manipulator or bathyscaphe.

Guide cable 2 lead into the upper part of the coupling device. Thus, the upper part of the coupling device is ready for operation. The lowering of the upper parts can be carried out simultaneously or alternately. The entire assembly is lowered along the guide cable 2, held in an upright position using the drawbar 23, 24. The catamaran winches select the guide cable 2, reeling it from the winch 15 of the sunken submarine (vessel). By the time the upper parts of the hitch of the sunken submarine (vessel) are reached, before reaching 15-20 meters, stop lowering. By command from a deep-sea vehicle or by video surveillance, the guide cable 2 is tensioned until the mushroom 1 is in a vertical position, regardless of how the submarine (vessel) is tilted. As soon as the mushroom 1 becomes in an upright position, stop the stretch and continue lowering the upper part, which, using the drawbar 23, 24, will occupy an upright position. The pins 29 will go under the cap of the mushroom 1 and the docking (coupling) will take place. High pressure hoses to the hydraulic cylinders are attached to one of the power cables of the catamaran through a certain distance to avoid their breakage from its own weight. Separate the submarine (vessel) from the ground. First of all, separation of that part of the submarine (vessel) is carried out, which, according to experts, is easier (bow or stern). After separation, the sunken submarine (vessel) is lifted synchronously to the surface. If necessary, a submarine (vessel) is fixed between the hulls of the catamaran with the help of additional cables.

The coupling release is done by pressing the pins 29 from the mushroom 1. For this, the upper part of the coupling device (figure 1)

freed from tension, lies on the mushroom 1, the hydraulic cylinders 27 are turned off. Axles 29 are pressed. The upper part of the coupling device (FIG. 1) rises, the locking plate 28 is removed. The slots on the inner pipe 24 are aligned with the slot on the outer pipe 23 and the guide cable 2 is removed from the drawbar. It is necessary to take into account the factor that when lifting a submarine (vessel) from the depths, it is necessary to make stops after a certain distance in order to make it possible to equalize the pressure inside the sunken submarine (vessel) with outboard pressure. In this case, the force of the power unit will be spent only on lifting the weight of the structure itself. If this is not taken into account, then as the sunken submarine (vessel) rises, the weight of the structure will increase due to the pressure difference, which led to a break in the tick-borne seizure of the Americans when they raised the sunken Soviet submarine in the South Pacific.

This coupling device makes it possible to rescue the crew, since there is no need to violate the tightness of the sunken submarine (vessel). Significantly reduced the time of the rescue operation, thereby increasing the likelihood of crew rescue. This utility model can be installed on submarines of both existing and newly built and lift submarines lying on rocky ground, in crevices lying on its side, nose up or down.

For information.

The rescue vessel is two powerful self-propelled barges with a carrying capacity of tens of thousands of tons. They should be interconnected by transverse decks, on

which are installed lifting equipment, as on the barge "Giant". The width between the hulls of ships (barges) should allow the exit of the superstructure of sunken boats (ships). One transverse flooring is installed in the bow, the other in the stern. The floorings on such a catamaran are located at about a quarter of the length of the catamaran from the bow and stern parts to create uniform loads on the catamaran and avoid breaking the rescue vessel. Two self-propelled barges / top / are needed to make it easier to lift a sunken ship. The catamaran must have an autonomous power station to provide electric power to lifting equipment, as well as a cable to secure the vessel to be lifted between the sides of the catamaran and to facilitate the supply of pontoons (if necessary). There should be deep-sea equipment (submarine "Baby" or bathyscaphe), which will be necessary in order to control the position of the vessel on the ground and the very process of controlling the operation of the coupling device. There should be two cranes and two winches in the bow and stern of the catamaran to work with the guide cable 2. There should be sets of high pressure hoses for hydraulic systems.
